CAR-COUPLING.

SPECIFICATION forming part of Letters Application filed April 18 1887. Serial No.235,280. (No model.)

To aZZ whom it may concern:

Be it known that I, DAVID BAKER, a citizen of the United States, residing at Freeport, in the county of Armstrong and State of. Pennsylvania, have invented certain new and useful Improvements in Oar-Couplers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. I

The special object of the invention is to improve the action of car-couplers by providing a link-raiser which shall render the coupling certain when two cars are brought together.

Figure 1 of the drawings isa plan view; Fig. 2, a side elevation, and Fig.3 a vertical longitudinal section.

1n the drawings, A represents the car, and B the draw-head, having top and bottom pinholes, b. Over the latterand on top of the draw-head is the guide-tube B, which carries on the inside near its top a pulley, G. The pin D has a chain attached at one end to its head, passing over the pulley O and secured to the upper end of a lever, E, which is hot- 0 tom-pivoted at e to the draw-head and has the opening ebetween its arms E E. Through the opening e passes the front end of the arm f on the shaft F, which has the hand-cranks ff at the sides. When the shaftF is turned, as shown in Fig. 2 of the drawings, the armf draws the leverE back and pulls on the chain d until the pin D is lifted from the link and allows said link to be withdrawn from the draw-head. On the other hand, when it is 0 desired to drop the pin into the link in order to couple two cars, the shaft is turned in an opposite direction downward, as shown in Fig. 3 of the drawings, when the weight of the pin will pull the lever forward and drop by its own gravity into the link.

guided at the rear in the keepers h. K is a guidebar' having the guide-slots k k for the rods H and the guide-slots k k for the linkraiser G. It has also an opening, k in which curely fastened.

When a car is to be coupled with another,

Fig. 2 of the drawings, and as the two cars approach each other the rods H strike the car carrying the link and are pushed back in their guides, so as to carry back the linkraiser G. The latter, asitsincline g is moved back over the bottom of the guide-slots k k',is raised until the end g ,lifts up and holds the described. 7
